ENVIRONMENTAL CHARACTERISTICS

TEMPERATURE RANGE—
Operating: +32°F to +120°F (0°C to +49°C).
Storage: +32°F to +158°F (0°C to +70°C).
RElATIvE HUMIDITy—
0 to 93% relative humidity.
Water or other liquids on the face of the detector
may decrease sensitivity.
ENClOSURE RATING—
IP67.
vIbRATION—
Compliance with FM Approval Standard FM 3260:
2000.
ElECTROMAGNETIC INTERFERENCE—
Highly resistant to radiated and conducted Electromagnetic
Interference (EMI). The detectors are immune to radiated
fields of 100 volts per meter, including amplitude and
frequency modulated (AM & FM) signals in the frequency
range of 1 MHz to 1 GHz. The detectors can operate in the
presence of conducted noise levels up to 1.0 VRMS in the
frequency range of 30 Hz to 250 kHz while the input
voltage, including noise, remains between 9 and 30 volts.
CERTIFICATION—
FM: Refer to Appendix A for details.
CE: See Special Conditions for Safe Use.

Special Conditions for Safe Use:
• The PM-5MPX Detector may only be installed,
15∞
connected or removed when the area is known to be
30∞
non-hazardous.

DETECTOR PERFORMANCE

DETECTION RANgE AND RESpONSE TImE

Best performance is achieved when the detector is
mounted so that the protected area is within the range, or
detection threshold distance (refer to Appendix A for test
result data), and within the 110° field of view (see Figure
2). The PM-5MPX detector can respond to fires in as little
as 25 milliseconds. Actual detection time depends on the
source of fuel, ignition sources and other aspects of the
initial fire stages. The detector has a typical response
time of <0.5 second to the fires specified in Appendix A.
The detector can respond most quickly to closer or larger
fires, but is unlikely to detect fires occurring further than
the indicated distance. The range is reduced when the
fire occurs close to the edge of the field of view of the
detector. At the edge (±55°) the range is reduced no
more than 50%.
The detector range to fires not listed in Appendix A
will vary and should be verified by fire tests using
the fuel in question. Please contact Detector
Electronics Corporation for further information.
